UNLABELLED The goal of this study was to determine whether differences exist in the frequency of paroxysmal atrial fibrillation and stroke (cerebrovascular accident) on days of different geomagnetic activity levels. Geomagnetic activity was divided into four levels: quiet (I degree), unsettled (II degree), active (III degree), and stormy (IV degree).(More)
Plasma viscosity was measured by the capillary method in 108 patients with ischemic heart disease. The highest value of plasma viscosity was found in 11 patients with severe unstable angina (1.66 +/- 0.068), while in 18 patients with less severe unstable angina plasma viscosity was lower (1.61 +/- 0.056; p less than 0.025). In 43 patients with acute(More)
The clinical features and course of 30 patients (26 men and 4 women) under 30 years of age (mean age 27.3 years) with an acute myocardial infarction (MI) are described. The most common risk factor among this group of patients was smoking in 20 patients (66%). The prevalence of the other risk factors was low: hyperlipidemia in four patients and family(More)
A method for the quantitative and qualitative determination of the number of aggregated platelets is described. One milliliter of venous blood was separated equally into two solutions. One solution composed of EDTA (ethylenediaminetetraacetic acid) and formaldehyde (solution F) contained reversibly and irreversibly aggregated platelets, and the second(More)
Objective: To compare the efficacy and adverse effects of ketorolac and diclofenac in the treatment of renal colic. Methods: In a double-blind, randomized clinical trial, 57 patients admitted to the emergency room for renal colic, received either 30 mg of ketorolac or 75 mg of diclofenac i.m. (intramuscularly). Evaluations were performed at 1, 2 h and 6 h(More)
Circulating aggregated platelets were assessed in 30 patients with stable angina, 22 with unstable angina and 50 with acute myocardial infarction (AMI). Fifty healthy volunteers and 20 noncardiac patients served as controls. One milliliter of venous blood was separated into 2 solutions: 1 composed of ethylenediamine tetraacetic acid (EDTA) and formalin(More)
Thirty-two patients with LAF were studied. Nineteen (59 percent) were male subjects. Mean age was 46.8 years. They were followed up for 2 to 16 years. On admission, most patients (94 percent) were symptomatic and had palpitations, nine had nonspecific chest pain, and five had syncope or near syncope. Left atrial size measured by echocardiography was less(More)
Circulating aggregated platelets (total, reversibly and irreversibly aggregated), the number of platelets per aggregate and "big" platelets were measured by a modification of the Wu and Hoak method in 42 patients on the first, second and fifth day of acute myocardial infarction (AMI). Among them, 30 had an uncomplicated course and 12 patients had(More)
Leukocyte endothelial interactions are essential for a normal immune response. It is known that this response is influenced by stress and that the latter induces demargination. We examined the question of whether stress demargination results from a decreased state of leukocyte adhesiveness. Included were various volunteers and patients under different(More)
Lactate dehydrogenase (LD, EC isoenzymes 1 and 2 and the LD 1:2 ratio were determined in 62 patients with recent myocardial infarction 24, 48, and 72 h after total serum LD activity had returned to normal values. From the results we could define two groups of patients. The first, 40 patients in whom proportions of LD-1 and LD-2 isoenzymes in serum(More)
